AUXILIARY PEDAL FOR PIANOS.

SPECIFICATION forming part of Letters Patent No. 628,963, dated J nly 18, 1899.

Application filed October 12, 1898. Serial No. 693,339. (No model.)

the most convenient to operatively control the piano, which I attain in the following manner:

Figure l is a side view of my invent-ion. Fig. 2 is a plan view. Fig. 3 is a perspective View of my invention.

A represents the foot-rest portion of my invention, which has the piano-contacting portion a, the forked arm portion a', and the horizontal holes a2 and a3 and the opening ai'.

B denotes the pedal-adj uster,which has the lever-holes l) and b therethrough, the adjusting-holes b2, and the retaining-teeth b3.

O representsthe removable adj usting-pin, which retains the pedal-adjuster by being passed through the hole d2 of the foot-rest fork and the respective ad.)` listing-hole through the pedal-adjuster.

D denotes the lixed adj lister-retaining pin, 'which passes through the hole d3 through the foot-rest fork and is retained ixedly therein.

E represents the foot-pedal, which has the pins e and e passing therethrough, the former to freely connect the foot-pedal to a connecting-rod and the latter to freely connect the foot-pedal to the pedal-adjuster, as shown in the drawings.

F denotes the piano-pedal-operating arm, which is pivoted to the pedal-adjuster by the pin f and which has its other end freely connected to a connecting-rod by the pin j.

Gr represents the connecting-rod, which con nects the auxiliary foot-pedal to the pianon pedal-operating arm that contacts the pianopedal,whieh is represented by the dotted lines shown in Fig. l and by the numeral l.

2 denotes the body of the piano.

rllhe use and operation of my invention are as follows: then a person cannot conven iently operate the pedals of a piano while retaining that position essential to grace and eilicient Inanipulation of the keyboard,by pootherwise, according to the will of the operator. In order to change the height of the auxiliary pedal and to secure such position after withdrawing the pedal-adjuster pin, all

.that has to be done is to cause the teeth of the adjuster to engage both sides of the iixed adjuster-retaining pin according to the elevation desired of the auxiliary pedal, and then after such positioning pass the movable ad juster-retaining pin through both the fork of the foot-rest portion of my invention and the pedal-adjuster,whieh becomes fixed in its position. The piano-engaging arm a passes underneath the piano and prevents the body of my invention tilting or swinging or moving from its position when being operated by the foot-that is, the auxiliary pedal is thus made .fixed in position. B y pressing down the auxiliary pedal the eonnectingrod transmits the movement to the piano-pedaloperating arm and such operates the piano-pedal, and the mechanism controlling the piano-pedal causes the auxiliary pedal to return to its normal position when the foot is removed from off the auxiliary pedal.

Having described Iny invention, l claiml. An auxiliary piano-pedal consisting of a foot-rest having an arm to contact the piano to retain the foot-rest body in position, and provided with a forked arm extending from the body, a pin passing through the forkedarm portion of the body and being fixed thereto, a removably-fitted pin passing through the forkedarm, an auxiliary pedal-adjuster entering the space of the forked arm, a series of notches pro vided on the edge of the pedaladjuster and engaging the fixed pin, a series of holes opposite the notches through the adj uster and engaging the removably-fitted pin, a piano-pedal-operating arm having one end freely connected to the lower end of the adjuster, a connecting-rod having its lower end freely connected to the opposite end of the piano-pedal-operating arm7 and an auxiliary pedal being Connected tothe upper ond of the adjuster, and having its opposite end freely connected to the upper end of the connect ing-rod, substantially as and for the purpose deseribed.

2. In an auxiliary piano-pedal, a foot-rest having an arin to Contact the piano to retain the foot-rest body in its position, and a forked arin extending from the body, in Combination with a pin passing through the forked arm and being fixed thereto, a removablyfitted pin passing through the forked ar1n,an auxiliary pedal-adjuster entering the space of the forked arm, teeth provided ou the edge of the pedal-adjuster and the adjuster thus engaging' the fixed pin, holes respectively opposite the teeth-notches through the adjuster,
